Scientists hope that the new LHC will allow them to launch rzaglyanut beyond the Standard Model

After repairs caused by the malfunction of the electrical network, the Large Hadron Collider was launched on Sunday again – the first time since 2013, with twice the power.

According to the scientists, using the collider the near future they will be able to get closer to unraveling the existence of “dark matter”.

Particle beams have already done a few laps on the parallel twin tunnel of the collider, but the first results of this work should be expected soon. Collision will occur in about a month, but then Collider expected to reach capacity in 13 trillion eletronvolt.

During start with renewed energy, scientists hope to look beyond the Standard Model.

more unknown

Scientists plan to reveal for the first time the so-called supersymmetric particles, or gluinos. If they appear in the collider, it will be the first direct empirical evidence of the existence of “dark matter” that predicted by the currently accepted model of the universe by the scientific community.

The Standard Model describes the physics of subatomic particles 17, including 12 fermions and bosons 5, the last of which, the Higgs boson was discovered during a previous run of the collider in 2012.

Professor Tara Shears of Liverpool University, working on the LHC, told BBC BBC: ” In each part of any experiment that we ever spent, we expected greater openness. But now it is especially important because with the discovery of the Higgs boson at the time of the last run, we found everything that our theory predicted only “.

In an effort to explain some mysterious properties of the universe, have been proposed theory lying beyond the Standard Model. However, the evidence of these ideas have not been found.

Scientists advise patience

This “dark energy” – the all-pervading power of allowing the universe to expand; and dark matter – the “web” that holds the visible matter at the site and explain why galaxies rotate faster than expected by scientists.

If supersymmetry theory finds its evidence during start LHC, some gaps in knowledge are filled.

Waiting

Through an unprecedented experiment, when the collision of particles in the LHC creates temperatures not seen since the Big Bang, physicists hope to find something that provide answers to their questions.

But most importantly – a residual product that scientists hope to capture. This is the neutralino, the lightest and most stable superparticles. According to the theory, that it is a major component of dark matter, it will help solve the problem of dark matter is needed to explain the relationship of galaxies, but not detected with the help of telescopes.

Not until May physics will have access to new information and Only then can begin its analysis.

Steven Goldfarb, who works in a research team Atlas, warns against too high expectations. He worked on the previous version of the collider, which nabyl launched in 1989 and says that if scientists expect to find evidence of the theory of supersymmetry and the Higgs boson.

“A lot of what we were looking for when we’re looking for now – he says. – In the end, we get more and more accurate data on the standard model. We were able to set boundaries, to help found the Higgs boson. But so far we have not made any discoveries, which would be a breakthrough. “

“This will be our task over the next several years,” – he added.

According to the scientist, now work will be more exploratory in nature. “We ask you to be patient! After all, this is our main job” – says Goldfarb.
